SMOKING-PIPE.

To all whom it may concern:

Be it known that I, GEORGE IVILDER CLAPP, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Smoking-Pipes, of.

which the following is a specification.

This invention relates to smoking pipes, particularly to that class of pipes having a plurality of smoke passages leading from the tobacco chamber to the mouthpiece and which have a self contained cleaning device connected to the mouthpiece, and adapted for removable insertion in any of the smoke passages for the purpose of cleaning such passage and on withdrawal therefrom to leave said passage clear and unobstructed.

My invention relates particularly to the cleaning device and the manner of connecting it to the mouthpiece, and the invention may be used in pi es having either a straight or a curved mout piece.

I will describe preferred embodiments of the invention and then point out the novel features in claims.

In the accompanying drawings: Figure 1 is a sectional view of a pipe with a curved mouthpiece showing one form of my improved cleaning device. Fig. 2 is a similar view of a pipe with a straight mouthpiece showing another form of my improved cleaning device. Fig. 3 is a plan view showing how the form of blank from which the cleaning device of Fig. 1 is made. Fig. 1 is a longitudinal section, on enlarged scale, of the cleaning device shown in Fig. 1. Figs. 1 and 4 are end views of Fig. 1. Figs. 5, 6, and 7 are views of the cleaning device shown in Fig. 1 as seen from diiferent sides. Fig. 8 is a side view of the cleaning device shown in Fig. 2 detached. Fig. 9 shows the several parts of the cleaning device in Fig. 8 separated. Fig. 10 is a section on the hne 10-10 of Fig. 9. Fig. 11 is a modified form of the cleaning device shown in Fig. 5. Fig. 12 is a side view, and Fig. 13 a sectional View showing a modified form of swivel connec tion for the wire cleaning device. Fig. 14 shows in cross section pipe stems with different arrangement of smoke passages.

A indicates the bowl of the pipe and a the tobacco chamber.

B is the stem which may extend from the bowl at an acute angle as in Fig. 1 or at a substantially right angle as in Fig. 2. The

mouthpiece is indicated by C and may be curved as in Fig. 1 or straight as in Fig 2. In all cases the stem B is provided with a smoke chamber 6 extending from the mouthpiece to a point a short distance from the tobacco chamber, and a plurality of smoke passages (Z lead from the inner end of the smoke chamber Z) to the tobacco chamber c. There may be any desired number of these smoke passages and in the present case I have shown two and such number will ordinarily be sufficient. As shown these passages are in substantially the same horizontal plane, but they might be arranged in a substantially vertical plane.

Referring now to Fig. 3, I have shown a form of blank which I employ for making the cleaner illustrated in Fig. 1. As shown the blank has a wide portion a: at one end, a narrower central portion y and a still narrower portion 2 at its other end, and preferably these portions will merge into each other on curved lines as shown. It will be seen that these blanks can be stamped out from a strip of metal with no loss except at the ends of the strip and the cleaner can thus be very economically produced.

In order to make the cleaner, the part m is bent into tubular form as indicated at e, the part y is bent into concave-convex form as indicated at f, and the part 2 into tubular form as indicated at g. The parts :0 and a may be bent in the same direction to bring their meeting edges on the same side, but preferably the part a will be bent in the opposite direction to bring its meeting edges on the opposite side of the cleaner as shown in Figs. 41, 6 and 7.

In order to connect the cleaner to the mouthpiece, I provide a split tube h, which may be secured to the mouthpiece in any suitable manner, and then, I form a swivel connection between the tubes 6 and h. As shown in Fig. 4-, the tube h is provided with an annular groove 2' and the tube It fits within the tube 6 and the outer end of the latter is crimped or bent over into the groove.

This construction prevents undue end-wise movement between the tubes 6 and 71, but

permits rotary movement between them. In

Fig. 11 the tube h which is secured to the mouthpiece receives the tube 0 and in this case the latter will be provided with an annular groove into which the outer end edge of the tube It will be turned or crimped.

This construction also prevents undue longitudinal movement between the tubes 6 and h but permits rotary movement between them.

The above described methods of forming a swivel connection between the mouthpiece and the cleaner, are illustrative only and I do not intend to restrict my invention to said forms of swivel joints.

In Figs. 2, S and 9, I have illustrated a cleaner made of wire. As shown in Fig. 8 this wire Z is bent between its ends to form two loops m and at, extending on opposite sides of the median line, and these looped portions are subjected to pressure to bring them into concavo-convex form cross sectionally of the wire as shown in Fig. 10. The wire Z is connected at one end in any suitable manner to a tube 6 which in turn may have a swivel connection to the mouthpiece as already described, or in any other suitable manner.

- The smoke chamber 6 will be of such diameter as to receive the widest portion of the cleaner in either form, and the smoke passages (Z will be of such diameter as to receive loosely either the tubular part 9 of one cleaner, or the free end Z of the wire Z in the other form of cleaner. The parts 9 and Z constitute cleaning fingers. The bore of the mouthpiece will be in alinement with the bores of the tubes 0 and h and the concaveconvex portion of either cleaner will conform substantially to the curvature of the smoke chamber, and always be to one side or the other of the smoke chamber Z) and consequently will offer no material obstruction to the free passage of smoke from either of the passages (Z to the mouthpiece.

Normally one of the passages (Z will be substantially filled by the cleaning finger, and the other will be unobstructed. As soon as the latter becomes obstructed by tobacco or from any other cause the mouthpiece is detached from the stem, the cleaner withdrawn to free the finger from the passage and then given a partial rotation to bring the cleaning finger in line with the other passage. The finger is then forced partially into the obstructed passage and the mouthpiece may, if necessary, be turned into proper position for use independently of the cleaner and then both may be forced inwardly to position. Obviously when the cleaning finger is withdrawn from a passage (Z, such passage will be substantially unobstructed for the passage of smoke.

By means of the swivel connection between the mouthpiece and cleaner the latter may be used with either a straight or a curved mouthpiece. In the latter case, if the connection between the mouthpiece and cleaner were substantially rigid and the cleaning finger were changed from one smoke passage to the other the curve of the mouthpiece would be in the wrong direction whereas with the swivel connection it can always be turned to curve in the proper direction. Many smokers after using a pipe a short time make dents in the mouthpiece with their teeth and if the mouthpiece be reversed to bring the under side upward, the teeth will not fit the dents and discomfort will result to the smoker. Vith the swivel connection the mouthpiece can be turned so as always to keep the same side upward.

In Figs. 12 and 13, I have shown another form of swivel connection between the wire Z and a tube h, which latterv will be connected to the mouthpiece. As shown the tube 7/ is provided with a flange [L and the wire is provided with a ring shaped portion Z eccentrically arranged at a right angle thereto and the flange is bent over onto the portion Z The part Z need not form a complete ring, but it should form more than half a ring to hold the parts in proper relation to each other. The tubes h and it will preferably be split tubes capable of a slight contraction in order to be forced into the bore of the mouthpiece and be retained therein by friction. This is an advantageous construc tion since it will enable the user of the pipe to entirely remove the cleaning device, without injury to it or the pipe, should he desire to do so for any reason.

It will be noticed that the cleaning finger in. all the forms is eccentrically arranged with respect to the swivel joint, the smoke chamber Z) and the bore of the mouthpiece, and that the tubular and concavo-convex portions of the cleaning device will by their engagement with the wall of the smoke chamber Z) serve as guides to bring the cleaning linger in line with the several smoke passages (Z when the cleaning device is rotated in the smoke chamber.

Obviously the concavo-conveX portion f might be omitted from the cleaning device shown in Figs. 1, l, 5, 6, 7 and 11 and the finger g be connected directly to the tube e; and while I prefer the form illustrated, I do not intend to restrict my invention to such specific form.

Having described my invention, I claim:

1. In a smoking pipe, the combination with the bowl and stem, of a mouthpiece, and a cleaner having a swivel connection to the mouthpiece, and extending through the stem into the bowl.

2. In a smoking pipe, the combination with the bowl and stem, of a curved mouthpiece and a cleaner having a swivel connection to the mouthpiece and extending through the stem into the bowl.
